BAB V KESIMPULAN DAN SARAN
V.1.
Kesimpulan Dari hasil percobaan memucatkan warna crude palm oil
menggunakan daun intaran, telah didapatkan hasil optimum, yaitu total warna yang dapat dikurangi sebesar 76%, kadar FFA menurun hingga 5,35%, dan PV menurun hingga 0,31 meq H2O2/kg minyak. Dari hasil-hasil ini dapat disimpulkan bahwa: 1.
Daun intaran terbukti dapat memucatkan warna crude palm oil dan dapat mengurangi kadar PV, serta FFA dalam minyak. Akan tetapi, penurunan FFA tidak signifikan.
2.
Daun intaran dengan delignifikasi dan treatment HCl dapat menyerap β-karoten dan PV lebih banyak jika dibandingkan dengan daun intaran tanpa delignifikasi dan treatment.
3.
Untuk treatment HCl, semakin besar impregnation ratio, maka semakin banyak juga β-karoten dan PV yang dapat terserap.
4.
Mekanisme penyerapan β-karoten dan senyawa hasil oksidasi diawali dengan pembentukan ikatan koordinasi pada Lewis sites yang menyebabkan pembentukan ion carbonium yang kemudian menyerap β-karoten dan senyawa hasil oksidasi dalam CPO.
V.2.
Saran Saran untuk pengembangan penelitian lebih lanjut adalah
modifikasi sifat kimia permukaan pada daun intaran dapat dilakukan dengan metode lain, misalnya dengan melakukan heat treatment menggunakan microwave agar dapat memperbesar kapasitas adsorpsi dari bubuk daun intaran. 51
